Hello Anas, thank you very much for your answer. I just tried it and copied all files you mentioned to my installation repository. After that, I used the GUI of autoyast to create the ISO image. Normaly my iso images are about 282mb large, if I use my xml-file. But after I copied those files from sp3 to my rep. directory the first image was 121mb, then 89mb and a third one foolish 32mb....notabene always the same xml-file! I mounted the iso image under /mnt and made a "du -h". 6.8M /mnt/boot/loader 56M /mnt/boot 2.5K /mnt/media.1 2.0K /mnt/UnitedLinux/i386 11K /mnt/UnitedLinux/i586 2.5K /mnt/UnitedLinux/noarch 5.5K /mnt/UnitedLinux/setup/descr 8.0K /mnt/UnitedLinux/setup 26K /mnt/UnitedLinux 56M /mnt It seems that yast2 could not gather one rpm listed in the xml-file. My questions. 1. Did you only copy the file driverupdate, linux, initrd from SP3 to /tmp/SLES and you didn't patch the whole /tmp/SLES with SP3? 2. How did you create your iso image? Using yast2 or via command line and mkisofs? Manuel
